The cultural method of shoot primordia was developed to maintain parental lines of F₁ hybrids for a long time without genetic variation. The shoot primordium including 1 or 2 leaf primordia was cultured in the semi-solid MS basal media with various combinations of BAP and kinetin. The cultures were maintained and proliferated in the 2 rpm drum shaker with illumination of 1,000 and 2,000 lux on the upper and lower part, respectively. Cultivar, Shinkuroda and male sterile lines had higher percentages of cell clumps than cultivars, Kazan and Flakkee-Vita-Longa. Higher concentrations of BAP and NAA showed higher percentages of cell clumps. C8(2.0mg/L BAP + 0.2mg/L NAA) was very effective in the percentages of cell clumps in all lines. Shinkuroda had higher percentages of plant regeneration among tested materials. Higher concentration of BAP and kinetin had higher percentages of plant regeneration. AR line has 93% of cell clump formation and 43% of plant regeneration. Plantlets has a average of 6 shoots and 3 roots.

Q fever is a zoonosis caused by Coxiella burnetii, Presenting as acute and chronic illness and it has been reported worldwide. Acute Q fever is usually asymptomatic or mild and self-limiting, but infective endocarditis is one of the most serious complications of chronic Q fever and can be fatal. Known risk factors for Q fever endocarditis are valvular heart disease, immunocompromised hosts, and pregnancy. There have been some reports on Q fever in Korea but there exists no report on Q fever endocarditis. We have experienced 2 cases of Q fever with underlying valvular heart disease; both Patients came to the hospital for evaluation of prolonged fever. Although Q fever and Q fever endocarditis are rare in Korea, Q fever endocarditis should be considered in the differential diagnosis of patient with infective endocarditis when causative microorganism cannot be identified.

Effect of Carbon black and Wax on Flow Properties of Copoly(styrene/butyl methacrylate) Composites

朴文秀 水原大學校 1997 論文集 Vol.15 No.-

화상재료에 널리 사용되는 공중합체의 하나인 styrene-butyl methacrylate(BMA) 공중합체에 카본블랙, 전하제어제 및 왁스를 첨가하여 고분자 복합체를 제조하였다. 전하제어제의 양을 1%로 고정하고, 카본블랙의 농도를 1%에서 5%까지 증가시킨 결과, 점도는 카본블랙의 농도에 따라 증가하는 형태를 나타내었으나, 온도에 따른 변화는 극히 미세하였다. 고분자 수지에 왁스를 첨가한 경우, 1에서 3%의 농도에서는 그 변화가 미미하였으나, 5% 첨가시에는 점도가 큰 폭으로 감소하였다. 이러한 감소는 왁스의 낮은 분자량과 고분자 수지 내에서의 상분리로 인한 윤활효과에서 비롯되는 것으로 사료된다.

문제: 뇌졸중 환자를 돌보는 간호현장에서는 급성기 뇌졸중 환자의 증상악화에 대한 조기사정과 적절한 대처가 매우 중요한 문제이다. 그러나 임상현장에서는 이를 객관화하고 수치화하여 모든 의료진이 의사소통할 수 있는 유용한 도구를 사용하고 있지는 못하는 실정이다. 이러한 문제를 해결하기위해 NIHSS(National Institute of Health Stroke Scale)를 신경과 진료의사를 중심으로활용하고 있지만 아직 간호현장에서는보편적으로사용하지 않고있다. 이에 뇌졸중환자간호에 NIHSS를 활용하여 뇌졸중 증상악화의 조기사정과 빠른 대처로 궁극적으로는 뇌졸중환자 간호의 질을보다 향상시키기 위하여 본활동이 시도되었다. 목적: 첫째, 간호사의 NIHSS 측정 신뢰도의 현수준을 점검하고 이를향상시키기 위한 프로그램을 개발·적용한다. 둘째, 간호사가급성기 뇌졸중환자에게 NIHSS 측정을 통하여 뇌졸중악화를 얼마나 예측할 수 있는지 분석하고 이를 향상시킬수있는 방법을 모색한다. 셋째, 궁극적으로 급성기 뇌졸중 환자의 증상악화의 조기 발견과치료를위한의료진의 올바른 대처지침을 마련하여 이를 적용한다. 의료기관: 경기도에 소재한 대학병원의 뇌졸중 집중치료실 질 향상 활동: 첫째, 간호사의 NIHSS 측정 신뢰도 향상을 위해 「NIHSS 간호사 교육 프로그램」을 마련하였다.

Flow Behavior of Polystyrene and poly(styrene-co-BMA) Depending on Molecular Weight and Composition

박문수 수원대학교 산업기술연구소 1998 산업기술연구소논문집 Vol.13 No.-

분자량의 증가와 함께 폴리스티렌의 전단점도는 증가하는 현상을 나타내었다. 전단속도와 전단점도와의 관계는 190,300 g/mol을 초과하는 고분자량의 경우 곡선의 형태(power-law)를 나타내었으나, 분자량이 111,400 g/mol인 폴리스티렌의 경우에는 전단점도가 전단속도에 무관한 Newtonian 유동형태를 보였다. 스티렌-BMA 공중합체에서의 스티렌의 양 증가는 점도의 증가 뿐만 아니라, non-Newtonian 유동현상을 유발하였다. BMA의 양 증가는 이와는 반대로 점도의 감소와 Newtonian 유동현상을 유도하는 것으로 관찰되었다. ML68HG 토너는 전단속도 전영역에 걸쳐 non-Newtonian 유동현상을 보였으며, 이는 수지의 가교에서 비롯되는 것으로 판단된다. 한편, 비가교된 SU98SBT4 토너는 전단속도에 관계없이 일정한 전단점도를 나타내었다.

저용량 Droperodol 의 지속적 정맥내 주사가 방사선 치료로 유발된 구토에 대한 효과 : As a Substitution for Granisetron for the Treatment of Gastrointestinal Symptoms from Palliative Radiation Therapy

문성록,박수경,정영표,김태요,최유선 圓光大學校 醫科學硏究所 1998 圓光醫科學 Vol.14 No.2

Background: Radiation therapy in palliative cancer management leads mainly to nausea, vomiting, dyspepsia and anorexia. Several agents have been used to treat above symptoms and sings. We assessed the usefulness of continuous intravenous infusion of low-dose droperidol, compared to granisetron for the control of gastrointestinal symptoms due to radiation therapy. Method: We devided 30 patients who developed gastrointestinal symptoms after undergoing palliative radiation therapy due to metastatic bone pain in two groups. In group G(n=15), the patients were injected granisetron(3㎎) and then injected it, 3㎎ per day. In group D(n=15), the patients were injected low-dose droperidol(0.25㎎) and then infused continuously at low-dose(1㎎/day) by the disposable continuous infusion pump. Result: There were no significant differences in the patient's satisfaction, improvement of appetite and incidences of side effects between two groups. Conclusion: The continuous intravenous infusion of low-dose droperidol can substitute for serotonin-receptor antagonist for the treatment of gastrointestinal symptoms during radiation therapy for cancer patients.

박문경,진덕희,김중균,공인수,김광현,홍용기 동의대학교 기초과학연구소 1997 基礎科學硏究論文集 Vol.7 No.1

A thermolabile alkaline phosphatase has been purified through steps of osmotic shock, ammonium sulfate salting-out, and DEAE-cellulose chromatography from the cultured broth of the marine Vibrio sp. M-96 strain. The optimal temperature for the enzyme activity was 35℃. The optimal pH was pH 11.0, and the range of pH stability was pH 10.4 to 12.0. Thermal inactivation occured within 6 minutes at 60℃. The enzyme was considerably inactivated by 0.1mM concentrations of Hg^2+, Ni^2+ and Zn^2+, whereas activated up to 234% by 1mM of Mn^2+. The activation energy and deactivation energy by the Arrhenius equation were 4.02 Kcal/mol and 9.09 Kcal/mol, respectively. The Km and Vmax values of the enzyme for p-nitrophenylphosphate were found to be 0.0465mM and 0.001335mM/min. respectively. Active from of the enzyme had a molecular weight of 57,000 dalton determined by the Sephadex G-200 gel filtration method.

The concentration of heavy metal were studied for the estimation of quality in herbal medicines which is Bupleuri Radix, Paeoniae Radix, Dioscoreae Rhizoma and Astragali Radix in products of north Gyeongbuk area. Also, we collected soils from several area in Gyeongbuk, and determined heavy metal concentration of soils by ICP. We compared with herbal medicines in products of Gyeongbuk and their soils. The average levels of heavy metal of herbal medicines in Gyeongbuk area are as follows : Mercury is 0.037㎎/㎏, Chromium is 0.093 ㎎/㎏, Nickel is 0.108㎎/㎏, Copper is 0.475㎎/㎏, Zinc is 3.14㎎/㎏, Manganese is 1.52㎎/㎏, Iron is 7.83㎎/ ㎏, and Cadmium, Lead and Arsenic is not detected. It was very lower in concentrations than those of average Korea area. For the heavy metals contents of Gyeongbuk area, in Gong Jung Ri, represented the higher level, it may be due to a near the road. The Cd contents in soil was not a wide difference. For the As and Pb contents in soil, Song Sa Ri (Bupleuri Radix) represented the higher level(0.68㎎/㎏, 1523㎎/㎏). Correlation coefficients of heavy metal contents in cultured herbal medicines and their soils did not give reproducible results. But the degree of correlation between a few heavy metal contents of Dioscoreae Rhizoma and their soil showed the good transfer from the soil.
